ELECTRIC GAS-LIGHTER.

Specification of Letters Patent.

Patented Nov. 28, 1905..

Application filed March 21,1905. Serial No. 251,311.

To aZZ whom it may concern:

Be it known that I, JOSEPH MLADA, a citizen of the United States, residing at Manitowoc, in the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Electric Gas-Lighters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to electric igniters for gas-burners in which sparking devices are movably supported above the burner in position to produce a spark in the body of gas flowing from the burner.

The object of the invention is to improve the construction and arrangement of the sparking devices,whereby they may be turned and held out of the path of the flame from the burner whenever necessary.

In the following specification I shall describe a preferred embodiment of my invention; but it is to be understood that the specific details of construction described and illustrated may be modified so long as the essential features and principles of the invention are retained.

In connection with the specification reference should be had to the accompanying drawings, in which Figure l is an elevation of a gas-burner pro vided with my improved gas-igniter. Figs. 2, 3, and 4 are top plan views of the burner and sparking electrodes, showing the latter in diflerent positions. Figs. 5 and 6 are sectional views of details of combination. Fig. 7 is a perspective view of a spring-controlled sparking electrode and its support, while Fig. 8 IS a view similar to Fig. 7, showing the electrode in another position.

The gas-burner is indicated by A, and the gas-supply pipe by B. These may be of any preferred shape or construction and need no specific description.

C is a split collar adapted to be firmly clamped on the burner by the screw 0, and this collar carries a bracket D, having lugs d, in which a sparking electrode E is supported to turn. As shown in Figs. 7 and 8, this electrode consists of a piece of metal bent between its ends to form two parts 10 and 11 at substantially a right angle to each other. The vertical part 11 is rounded at each end to fit in holes in the lugs d to turn freely therein, and between the lugs it has flattened sides,

in Fig. 4.

preferably at a right angle one to the other. The part 10 forms a contact-arm and is adapted to extend across the burner, as in Figs. 2, 3, and 4:, or be turned to one side thereof, as in Fig. 8 and dotted lines in Fig. 2.

F is a fiat spring secured at one end, preferably its upper end, to the bracket D, and its free end is adapted to engage a flattened side of the portion 11 of the electrode E, and thereby hold said electrode yieldingly in position.

The supply-pipe B is provided with a cock G in the usual manner for controlling the su pply of gas to' the burner, and to this cock the other sparking electrode H is secured. This electrode is also bent to provide a contact-arm it, adapted to be moved across the burner to engage the arm 10 of the electrode E. The upper end of the electrode H is supported by a bracket 6, provided with insulating material 75, through which the electrode passes loosely. By turning the cock G from closed position, as indicated in Fig. 1, the contact-arm /L of the electrode will be moved from the position indicated in Fig. 2 to that indicated in Fig. 4, and during such movement it will engage the arm 10 and move it to the position indicated in Fig. 3, at which point the two arms are supposed to disengage and produce the spark, and the spring F by its action on the flat side of the portion 11 of the electrode will at once return the arm 10 back to its original position,as indicated It will be observed that in either of its extreme positions the arm h is outside the path of the flame from the burner. It now from any reason it is desirable to also move the arm 10 of the electrode Eoutside the flame area, such arm may be moved through an arc of ninety degrees in either direction, whereby the spring F will be caused to engage a fiat side of the portion 11 of the electrode at a right angle. to that previously engaged thereby, and the arm 10 will then be yieldingly held outside the path of the flame.

The electrode 10 may be turned out of the path of the flame by means of any suitable instrument adapted to engage and either push or pull it to the desired position. By turning the electrode out of the path of the flame it will not be subjected to such intense heat, which eventually would burn it away and render it useless as an electrode. Furthermore, it will not be so liable to become coated with carbon, which would detract from its efiiciency.

w and y are the conducting-wires, leading from any suitable supply of electricity. (Not shown.) The wire :0 is shown as connected to the supply-pipe B and is therefore in electrical connection with the electrode H. The wire 1 is covered and extending through the pipe B to a binding-screw 12, which extends through an insulating-plug l3, fitted in the wall of the pipe adjacent to the cock G. The electrode H is connected to the cock G by means of a bracket 14 by means of a screw 15, but the screw 15 and electrode H are bothinsulated from the bracket by insulation 16. The binding-screw 12 is electrically connected to the screw 15 by a flexible-wire connection 17. An open circuit is thus formed through the wires 00 3/ and the sparking electrodes E and H, which will be closed when the arms 10 and it are engaged. Any other system of wiring may be employed.

Having thus described a preferred embodiment of my invention, 1 claim 1. The combination with a gas-burner and its controlling-cock, of an electric igniter,comprising a sparking electrode connected to said cock and having an arm movable across the gas-outlet from the burner, and a sparking electrode supported on the burner and having an arm also movable across the said gas-outlet, and means for yieldingly holding said arm above said outlet in the path of movement of the firstnamed arm, substantially as described.

2. In an electric igniter for gas-burners, a

sparking electrode, and means for yieldingly holding it either within or without the flame area of the burner, substantially as set forth.

3. In an electric igniter for gas-burners, a sparking electrode supported to have turning movement on the burner, and a spring for yieldingly holding said electrode within or without the flame area of the burner, as set forth.

4. In an electric igniter for gas-burners, a sparking electrode supported to have a turning movement on the burner and having flattened portions at an angle to each other, and a spring also supported by the burner to engage the said flattened portions and yieldingly hold the electrode in different positions, substantially as described.

5. The combination with a gas-burner, of a bracket supported thereon, a sparking electrode supported by said bracket to turn therein, said electrode having flattened sides at an angle to each other, and a flat spring connected at one end to said bracket with its free end in position to engage either of said flattened sides, substantially asset forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
